Abstract

Results of studies of radiative decays of the ψ(3684) using the SLAC-LBL magnetic detector at the electron storage ring SPEAR are presented. There are three high-mass states produced in ψ(3684) radiative decays, with masses of 3414±3, 3503±4, and 3551±4 MeV where the errors given do not include an overall mass-scale uncertainty of ±4 MeV. There is some evidence for a fourth such state at either 3455 or 3340 MeV. The branching ratio for ψ(3684) radiative decay into the state at 3414 MeV is found to be (7.5 ± 2.6)%. The decay modes of these states into hadrons and into γψ(3095) are studied, yielding information about the branching ratios, spins, and parities of the states. The results are interpreted in the charmonium picture of the high-mass states.
